WATER-HEATING ATTACHMENT FOR GAS-STOVES.

SPECIFICATION forming part of Letters Patent No. 417,197, dated December10, 1889.

Application filed February 11, 1889. Serial No. 299,501. (No model.

To all whom it may concern.-

Be it known that I, JAMES HENRY McNUrT, a citizen of the United States,residing at Alameda, in the county of Alameda and State of California,have invented certain new and useful Improvements in ater-Heating At'tachments for Gasoline-Stoves, of which the following is aspecification.

My invention relates to improvements in water heating attachments forgasoline stoves; and it consists in certain novel construction andcombination of a permanent water-heating coil and burners, ashereinafter fully described, to afford a constant supply of hot waterwithout retarding or otherwise affecting the regular cooking operationin any part of the stove.

The following description explains the nature of my said invention andthe manner in which I have applied the same for use, the drawings thataccompany and form a part of this specification being referred to byletters.

Figure 1 represents a gasoline-stove of the kind having a bakebven andabroiling-space below it, with my invention arranged and combined thereinready for use. Fig. 2 is a plan, on a larger scale, of the heater-coil,but with the water-heating burners removed from above it. Fig. 3 is avertical cross-section at about the line 00 at, Fi 2, with the topburner in position.

My improvement is adapted more particularly for gasoline-stoves in whichthere is an oven or baking and roasting compartment, and I havetherefore illustrated in the draw-, ings an application of my completedevice to one of the best-known styles of stoves of this character. Theparts of the stove-such as the gas-generating apparatus, burners, andregulating-valves, the supplytank and connections-I shallnotdescribe,however, as the special style or construction thereof formsno part of the present invention, and the same may be of any suitableconstruction for producing the desired object.

In carrying out my invention I arrange in side of the even of thesestoves a heatencoil A, composed of pipes laid closely together inparallel manner, connected at the ends by U joints or couplings a a, andhaving the terminals connected with the hot-water reservoir or boiler Bin the usual manner by pipes C (P, for proper circulation of the Waterfrom the boiler through the coil. Directly over the coil and between itand the bottom or lowermost shelf or rack in the oven I place burners DD, facing the pipes, and with their burnenorifices as close aspracticable to the top surfaces of the coil, the burners being connectedby means of a pipe Z with the gasgenerating apparatus of the stove. Inthis position the coil is directly over the burners E E, that supplyheat to the oven, and are also used for broiling purposes. Theselastmentioned burners, however, as now placed, have their backs turnedtoward the oven, and their faces or burnerorifices setting downward tofurnish top heat and flame-for broilin g, so that alone they are notonly insufficient to heat the coil properly, but the pipes of the coil,by virtue of their position and close relation to the burner and to oneanother, act to shut off and deflect the heat away from the oven-spaceabove. The top burners D are applied, therefore, for the double purposeof securing effective heating action on the coil, for the replacingwhatever proportion of heat is taken away from the oven-space by thecoil that is thus placed over the oven-burners, as well as forcontributing gen rally to the proper operation of the oven.

In practicethe additional set of burners I) can be connected to the pipeZ, that supplies the main or lowermost set 'of burners by a suitable Tcoupling Z.

The hot-water boiler and all the connections are of the usual character,and no special description of the same is necessary, as any personfamiliar with setting water'heating boilers for domestic purposes willreadily understand from the foregoing description how to apply andarrange for practical operation my said apparatus.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. The herein-described water-heating deviccor attachment forgasoline-stoves, consisting of a water-heating coil arranged inside theoven, the oven-heating and broiling burners, above which the coil islocated, and the burners placed for operation over the said coil andconnected with the gas-generating gas-generating apparatus of the stove,subapparatus of the stove, substantially as set stantially as described,for operation as set forth. forth.

2. In combination with the gasoline-stove In testimony that I claim theforegoing I 5 having the broilingand oven-heating burners have hereuntoset my hand and seal.

in the bottom thereof, a Water-heating boiler,

, 1 T T T V a heating-coil connected with it and placed JAMES HEB RX MOBU1 for operation directly above said burners, and Vitnesses: a set ofburners (one or more) placed directly CHAS. E. KELLEY, IO over the saidcoil, having connection with the E. DANGLADE.
